My 02 Zetec is stuck in open loop fault. My o2 sensors are also reading some interesting voltages. Sometimes while engine running there is 0v both sensors, when I turn off the car with key in I read .005v both or .065v both. Also with checking connection and wires it has read 0v upstream and 1.250v down, this was key in engine off so I started it to see what happens and upstream hovered below .050 volts And downstream stayed at 1.250v. I have no ideas of what to make of these readings. It runs like crap and is not drivable. I tried to find melted wires and opened some of the loom but came up with nothing. Not sure if relevant but TPS reads at 18%.
